摘要：
In order to study the flutter characteristics of diamond back wing, a first order code has been developed to interface a structural model with an unsteady Navier-Stokes fluid model. FLUENT 6.2 was chosen to calculate the unsteady aerodynamics. NASTRAN was chosen to analyse the structures. Initial testing of this code has been completed on AGARD 445.6 wings. Computational results agreed well with the experiments and the computed results of other researchers. The procedure is thus demonstrated to be accurate. The code was used to analyse the flutter characteristics of diamond back wing and obtained the flutter velocity and frequency of diamond back wing.
